Hans: You could try an old aircraft solution (as I did). Thoroughly clean both mating surfaces. Coat one side with Permatex Hi-Tac gasket sealer. Lay a silk sewing thread in the Hi-Tac about in the middle of the mating surface and run it around that surface. Keep the thread inboard (oil side) of each stud as you come to it. When you return to the beginning of the thread, cross the two ends so there is no break in the continuity of the thread. Coat the other mating surface with the Hi-Tac and put them together. Torque the nuts per the manual and diametrically like you were tightening a road wheel or a cylinder head. Guaranteed not to leak and is still easy to disassemble. | ||

While you are there Hans, inspect the gears. My lower transfer gear had tiny cracks all the way around the outside. Needless to say I replaced all three. | ||

Tom: No, it's ME weeping. Everytime I get under the car. | ||

btw, make sure it is not the studs weeping - they tend to do that | ||

A mechanic just told me about a product named, if I'm remembering correctly, "Toyota Super Sealer". (I may have screwed up the name a bit.) It's sold at Toyota dealers, hence the name. Duh. Anyway, altho it's intended to be used like conventional silicon auto sealer, he's had good luck smearing it on the outside of close fitting leaky parts. I just might try this instead of removing the cover. | ||

As JRV said watch the gear direction. It may well come out with the cover. Also watch the thrust bearing, they are directional as well. | ||

JRV: I hadn't planned on removing the gears - do I have to for some reason? All that is wrong is that the stupid cover is leaking. And, yeah, it looks like a no-brainer, but I just wanted to make sure. | ||

No tricks,,,just make sure you put the center gear back in facing the correct way, otherwise they get noisy...one side of the gears is scribed, the other not. | ||

GT4 leaks are like that 'chest of drawers' scene in the old Three Stooges movies: Push one drawer in, and another pops out, etc. | ||

I've got a leak on the transfer gear cover. Anything of note to R&R it? Looks very straight forward - a few nuts, pull it off, reseal, re-install. Any gotchas that aren't obvious? |
